(2) 8-Bit, 3-State Access Space: Figure 6.6 shows the bus timing for an 8-bit, 3-state access
space. When an 8-bit access space is accessed, the upper half (D15 to D8) of the data bus is used.
Wait states can be inserted.

Note:
* For external address space access, this signal is not output when the 256-kbyte expansion area
CS256 (CS256E = 1)
CPCS1 (CPCSE = 1)
is accessed with CS256E = 1 and when the CP expansion area is accessed with CPCSE = 1.
